Patented Oct. 4, 1932 CLEMMA R. RANEY, OF .RIVERSIDE, AND REX 1B. ASSIGNORS T INTERNATIONAL HARVESTER JERSEY HITCHCOGK, OF CHICAGO, ILLINOIS, COMPANY, A CORPORATION OF NEW -EAR GONVEYECR FOR HUSKING ROLLS Application filed April 19,

This invention relates to corn pickers. More particularly relates to improvements in an ear forwarder adapted to oper-' ate over the husking rolls of a corn picker.

The principal object of the invention isto provide an improved ear forwarding means adjustable with respect to the husking rolls.

- Another object is to provide such a device which may be pivotally mounted on its driving shaft whereby it may be lifted unto an upright position so as to gain access to the husking rolls forcleaning or repairing'without disconnecting "the driving mechanism.

The objects of the invention are attained by theconstruction illustrated in the drawing and described in the detailed description to follow.

Figure 1 is a plan view of a portion of a conventional husking unit in which the invention is embodied;

F'gure 2 is an elevation of the structure shown in Figure 1;

Figure 3 is an enlarged elevation of the conveyer adjusting means; and,

Figure 4 is a section showingthe same elements as Figure 3.

The device of this invention is suitable for use in connection with any of the well known corn husking units which embody a series of parallel husking rolls. The drawing illustrates the invention as embodied in a husking unit such as shown in the copending U. S. application Serial No. 435,728, filed March 14, 1930. As the construction and mode of operation of such husking units are well known, only such parts have been shown as are associated with the ear forwarding device of this invention.

A pair of downwardly extending frame members 1 in the form of angle 'bars and a second set of angle bars 2 having vertical portions joining the bars 1 form the frame structure which supports the ear forwarding means. Plates 3 and 4 are attached to the frame members. Two outer husking rolls 5 positioned adjacent the frame members 1 and 2 near the husking rolls 6 positioned at a lower level than the rolls 5 and in cooperating position with respect thereto illustrate the husking means. The husking 1930. Serial No. 445,741

rolls may be driven in any well known manner. A shaft 7 is positioned transversely of the husking rolls near the upper end thereof and is rotatably mounted with respect to the plate members 4. A chain sprocket 8 is attached to one end of the shaft 7 and comprises means for driving said shaft. A frame structure for supporting the conveyer of the ear forwarding device consists of flat side bars 9 and the braces 10 rigidly secured to said bars and to each other. The bars '9' are rotatably mounted at their upper ends on the shaft 7. At the lower end of the bars 9 a shaft 11 is mounted for rotation in bearin brackets 12 which are rigidly secured to the bars Chain sprockets 13 are rigidly secured to the shaft 11 near each end on the inside of the brackets 12. Similarly the chain sprockets 14 are rigidly attached to the endsofthe bar 7 in alignment with the sprockets 13. I r l .An endless conveyer extends around the frame structure. The conveyer consists of a pair of chains 15 which pass over the chain sprockets 13 and 14 and a series of slats 16 secured to the chains and extending there between. A series of resilient flaps 17 are attached at spaced intervals to the slats 16.

At thelower end of the frame structure a bracket 18 is secured to each of the frame bars 9 near the lowervend. A bearing 19 is mounted in each ofthe brackets 18 and a shaft 20 extends through said bearings and laterally beyond the brackets 18 atieach side of the frame structure. Cain members 21 are-secured to each end of the shaft 20 and are positioned to engage the respective frame members '1, as clearly shown in Figures 3 and 4-. The shaft 20 is square in cross section to facilitate the mounting. of said cam members. T

An adjusting means for changing the rel ative angularp'osition of the cam members 21 comprises abracket 22 rigidlysecured to one of the sidebars9 and an operating and lockinglever 23. The bracket 22 has a laterally projecting engaging edge in the'form of an are having a series of spaced notches 24. The lever-'23 is of a thickness which permits its engagement .withthe bracket 22 forwardingzmeans with respect to shaft 20 and into engagement with the" notches" 245' in' the" bracket 22. A ledge 29'01'1 the bottom of the lever 23 forms a stop to limit this rotating movement.

The operation of this device will beevident from the preceding description.

Through the application of power and a driving chain, not shown, operatively en gaging the chain sprocket 8, the shaft 7 iscon-tinuously rotated. As the bars 9, which 5 form'apart of the frame structure,- a-re ro-- tatably mounted on the shaft 7, the rotation ofsaid shaft does not affect the position of the frame structure. The chain sprockets M, which are rigidly mounted on the shaft 5 7, engage the chains 13 of the con-veyer continuously operate said conveyer. At the lower end of the frame structure, the cam members 21 engaging the frame members I support the frame structure and likewise the -'T- conveyer in spaced relation above the husking rolls 5 and 6. The shaft 7 is rotatedto drive theconveyer with the portion adjacent the husking rolls moving? downwardlyi Ears of corn delivered to the hnsking rolls by any suitable means are engaged by the resilient pressure element 17 on the c'oriveyer. and are maintained. in close contact with the huskingrolls.- It is sometimes desirable to adjust: the; position of the eonvey'er' and ear the huskin-grolls. By disengaging the lever 23 from the bracket 22, the forward end of the frame structure carrying the coiiveyer may be ad justed within a vertical distance equivalent to the difference in radius of the engaging surfaces of the cam members 21.-

It is sometimes necessary to inspect and repair or clean accumulated material from the husking rolls. In the device of this inventi'on the lower end of the frame structure and the conveyer carried thereby may be lifted upwardly, as shown by the dotted position in Figure 2. It is also apparent that the frame structure may be lifted while the mechanism is in operation, thereby bring ing the portions of the husking rolls into view for inspection or repair. 1

Although a preferred embodiment of the invention has been illustrated and described,

it is to be understood that any construction 'falling within the scope of the appended claims is contemplated as the invention.

What is claimed is:

L In a corn picker having two adjacent inclined husking rolls mounted for operation between said frame members, an ear conveying means comprising a driving shaft mounted for rotation on said frame members transversely of the husking rolls at the upper end thereof, a frame structure pivotal-1y attached at one end to said shaft, s'aid structure consisting of a pair of spaced bars and braces rigidly connected to said bars, a shaft mounted for rotation atthe'lovver end of the frame structure, spaced chain sprockets" mounted on said shaft, spaced chain sprockets rigidly attached tothe driving shaft, an endless conveyer extending. around the frame structure and operatively engaging said sprockets, resilient pressure elements carried by said conveyer, means for adj-ustabl'y supporting the lower end of the frame structure thereby regulating the-'heigl'it at which the conveyer operatesabove; the bushing r'olls, said means including brackets projecting laterally beyond the conveyer ateach side of the frame structure, and means to simultaneously alter the: vertical position of saidbrackets relativeto the frame members.-
